Detailsinfo

A vulnerability classified as problematic has been found in strongswan (Network Encryption Software). Affected is an unknown part of the component IKE Daemon. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. CVE summarizes:

The ASN.1 parser (pluto/asn1.c, libstrongswan/asn1/asn1.c, libstrongswan/asn1/asn1_parser.c) in (a) strongSwan 2.8 before 2.8.10, 4.2 before 4.2.16, and 4.3 before 4.3.2; and (b) openSwan 2.6 before 2.6.22 and 2.4 before 2.4.15 allows remote attackers to cause a denial of service (pluto IKE daemon crash) via an X.509 certificate with (1) crafted Relative Distinguished Names (RDNs), (2) a crafted UTCTIME string, or (3) a crafted GENERALIZEDTIME string.

The weakness was shared 06/24/2009 (Website). The advisory is shared for download at debian.org. This vulnerability is traded as CVE-2009-2185 since 06/24/2009. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 67887 (Oracle Linux 5 : openswan (ELSA-2009-1138)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117052 (CentOS Security Update for Openswan (CESA-2009:1138)).
